WATER TURBINE.

Application filed May 2, 1922 Serial No. 557,893.

T 0 all whom it may concern Be it knownthat we, THOMAS J. JoLLY and WILLIAM F. Frrzrarnloir. citizens of the UnitedvStates, residing at Ulysses, in the county of Butler and State of Nebraska,

have invented new and useful Improvements in Water Turbines, of which the following is a specification. v

In carrying out the present invention it is our purpose to provide a- 'water turblne wherein the flow of water to the wheels of the turbine may be controlled at will, so that the speed of the turbine wheels may be varied in accordance with the load thereon. It is also our. purpose to provide a water turbine wherein a number of wheels arranged in a vertical series may be acted upon by the water successively and rotated n relatively opposite directions so as toobta n the maximum power from the water and wherein these oppositely rotating turbine wheels will be connected with thelpower shaft in such manner as to impart a continuous and uninterrupted uniform motion to the shaft. 7

A further objectof our invention is to improve and simplify the general construction 'of water turbines and to provide a, turbine wherein the component parts will be so arranged and corelated ass-to reduce the possibility of derangement to a minimum.

With the above recited objects in view, and others of a like nature, the invention resides, in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended elaim. la he c mp ny dr =1 l Figure 1 is a vetrical sectional view through a water turbine constructed in accordance with our invention parts being shown in elevation. v

Referring now to the drawings in detail, 1 designates a. vertical casing having the upper end formed to provide an inletf or the water and the lower end providing an outlet or discharge.

Arranged within' the casing 1 at the lower end thereof is a step bearing 2 and rotatably mounted in the step bearing 2 is the lower end of a vertical shaft 3 extending upwardly through thecas; ing 1 at the center thereof. Fixed upofithe vertical shaftf3 immediately above the step bearing 2 is a turbine wheel 4 comprising, in, the present 'instance 'ahollow hub-like portion Sand blades oradiating from, the hub and spaced apart'equal distances, around t These b ades 6 are arr nge a an angle to ,the vertical so that as the wa'ter falls thereon 'the wheel l'lwill be rotatedlin one direction. Loosely mounted upon the shaft 3 above the Wh e 4, is a second water wheel? composed. in the present instance,

of a hollow hub-like portion 8, and blades9 radiating from the hub and disposed a t an angle to the vertical and pitched ina direction opposite to the blades 6 of the wheeli l,

so that the wheel 7 will be rotated in, a direction opposite to the direction of rotation of the wheel 4. In the present instance the blades 9 are arranged closer togetherlthan the blades of the wheelie, so that the, water may act to its maximum capacity upon the wheels 7 and 4; in their vertical; series. thereby enabling the wheels to be rotated about their axes with the effect to, deliver the maximum power.

Loosely surrounding the, shaft 3 above the I wheel 7 isa sleeve 10 adapted for. rotation around the shaft and connected to the hub portion of the wheel 7, so'a-s to be revolved from such wheel. In the present instance,

the lower end of the sleeve 10 is formed with an enlarged annular collar 11 and the lower end of the collar 11 is formed-at diametrically opposite points with dependingteeth 12 that engagein notches l3formedin the 3" upper. surface of the hollow hub portion 8 of the water wheel '7. These interengaging teeth and notches forma connection bet-ween the water wheel 7 and the sleeve 10.

Keyed upon the upper end of thesleeve 10 is a-beveled gear 14 and keyed upon t-he shaft 3 above the beveledgea'r 14 is a beveled gear 15 These beweled'v gears 14 and 15 mesh with a beveled gear 16 keyed uponone end of a horizontal power. shaft 17 journaled in a bearing lS'QQL liQd by the inner wall of the casing 1, the shaft 17 extending outwardly from the casing so that the power may be taken therefrom in the operation of the water wheels.

In the present instance. the shaft 3 is braced at a point between the beveled gears 14 and 15 by means of a bearing 19 that is carried by a spider 20 arranged within the casing 1. In this instance the outer ends of the arms of the spider 20 are formed with feet 21 engaged in recessed blocks 22 secured to the inner wall of the casing 1. as clearly illustrated in Figure 6 of the drawings.

In order to control the flow of water to the blades of the water wheels so that the speed of such wheels may be varied, we employ a valve mechanism which, in the embodiment of our invention selected for illustrative purposes comprises a cone shaped housing 23 having the apex formed with an upstanding flange 24 encircling the sleeve 10 above the collar 11 and the lower edge formed with an outstanding horizontal plate 25 formed with radial slots 26 spaced apart equal distances and through which the water is adapted to flow to the blades of the wheel. The outer edge of the plate 25 rests upon a circular flange 27 carried by an annular band 28 engaged against the inner Wall of the casing 1 and appropriately secured thereto. Mounted upon the plate 25 is an annular valve plate 29 formed with radial slots 30 spaced apart around the plate 29 and adapted to be moved into and out of registration respectively with the slots 26 in the plate 25. The inner edge of the plate 29 engaged in a groove 31 formed in the lower edge of the cone 23, so as to maintain the valve plate in proper position at all times. At a suitable point in its length the valve plate 29 is formed with a rack 32 engaged by a pinion 33 on one end of a shaft 34 journaled in the casing 1 and havlng its outer end equipped with a hand wheel 35.v By means of the construction of valve mechanism just described it will be seen that when the hand wheel 35 is rotated motion will be imparted to the shaft 34, pinion 33 and rack 32 to the valve plate 29 whereby the latter may be adjusted to move the slots therein into and out of registration with the slots 26 in the plate 2 5 and to vary the size of the openings formed by the slots so that the flow of water to the water wheel may be permitted, cut off completely and regulated at will.

In practice, the head of water in the upper end of the casing 1 tends to flow from the valve mechanism and in the engagement with the blades of the water wheels 7 and 4, and when the valve mechanism is open the water acts upon the blades of the water wheels to turn the same in,relatively reverse directions, thereby imparting motion to the shaft 3 and sleeve 10, and this mo tion, is converted into a continuous rotary motion in one direction by means of the beveled gears 14, 15 and 16, so as to impart an uninterrupted motion to the shaft 17. from which power may be taken for any desired purpose.

By means of the Valve mechanism herein before described it will be seen that the flow of water to the wheels may be regulated and controlled.

If desired, suitable anti-friction bearings may be provided between the shaft 3 and the sleeve 10 and between the confronting surfaces of the hub surfaces of the hub portions of the water wheels 7 and 4, as clearly illustrated in Figure 2 of the drawings. This is so also in the step bearing.

While we have herein shown and described one preferred form of our invention by way of illustration, we wish it to be understood that we do not limit or confine ourselves to the precise details of construction herein shown and described, as modifications and variations may be made within the scope of the claim and without depart in from the spirit of our invention.
